Filter file according to pattern

Hello

I have an input file which is tab delimited.In my unix script I have search for a particular pattern.If it is NOT present then I have to write in an output file.
Eg.Input file is :
Code:
123  hello 7779 hi hkjh88 hahah
678  hello 90845 ti hkjsdfh 9324

And the search string is "123 hello hi".If all these are present in the particular line then the line should not be written to the output file.All other lines should be written.The output file will look like:
Code:
678  hello 90845 ti hkjsdfh 9324

The fields are present at fixed position of the tab-delimited line.In the above ex 1,2 and 4.
Plz help
Thanks

Clear on the input and output . u said the files are pipe delimeited
Code:
123 | hello |7779 |hi |hkjh88 |hahah
678 | hello |90845| ti |hkjsdfh |9324

u need to search for the string
Code:
123 |hello| hi

whole string to match exactly or each field shouls me present or each field should me present at the correct position ? clear on that

The file is a tab delimited not pipe delimeted.The fields will be present in the fixed positon.It will not be present anywhere else.So we can search the full line itself with the 3 patterns or the particular field also with the the corresponding search pattern.I guess the 1st option is much better.
